4563: =head1 Bubble sheet grading routines
4564:
1.424 albertel 4565: For this documentation:
4566:
4567: 'scanline' refers to the full line of characters
4568: from the file that we are parsing that represents one entire sheet
4569:
4570: 'bubble line' refers to the data
4571: representing the line of bubbles that are on the physical bubble sheet
4572:
4573:
4574: The overall process is that a scanned in bubble sheet data is uploaded
4575: into a course. When a user wants to grade, they select a
4576: sequence/folder of resources, a file of bubble sheet info, and pick
4577: one of the predefined configurations for what each scanline looks
4578: like.
4579:
4580: Next each scanline is checked for any errors of either 'missing
1.435 foxr 4581: bubbles' (it's an error because it may have been mis-scanned
1.424 albertel 4582: because too light bubbling), 'double bubble' (each bubble line should
4583: have no more that one letter picked), invalid or duplicated CODE,
4584: invalid student ID
4585:
4586: If the CODE option is used that determines the randomization of the
4587: homework problems, either way the student ID is looked up into a
4588: username:domain.
4589:
4590: During the validation phase the instructor can choose to skip scanlines.
4591:
1.435 foxr 4592: After the validation phase, there are now 3 bubble sheet files
1.424 albertel 4593:
4594: scantron_original_filename (unmodified original file)
4595: scantron_corrected_filename (file where the corrected information has replaced the original information)
4596: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4597:
4598: Also there is a separate hash nohist_scantrondata that contains extra
4599: correction information that isn't representable in the bubble sheet
4600: file (see &scantron_getfile() for more information)
4601:
4602: After all scanlines are either valid, marked as valid or skipped, then
4603: foreach line foreach problem in the picked sequence, an ssi request is
4604: made that simulates a user submitting their selected letter(s) against
4605: the homework problem.
